Just been down to sywell this morning, and have to say, there was far more interest on the Airbox stand than any of it's competitors .....
I have tried the free trial of sky demon, yes it's good, but do try the free trail of the iPad app for Airbox...... I think you will be pleasantly surprised, they are the actual caa charts and street level OS maps.....
It knocks spots off the sky demon..
Well done guys at Airbox,
Nelly..
